Manifesto for Scaling up Prefab NetZero Retrofits across Europe
Our Common Vision
In a sustainable, fossil-free future, energy-efficient and zero-emission buildings will be an active part of a healthy planet. Beyond achieving climate neutrality, they should function as energy producers and foster vibrant, livable neighborhoods worldwide. Innovation is urgently needed to accelerate energy efficiency and circularity in Europe’s building sector, contributing to the achievement of climate targets.
Prefab NetZero Retrofits as a Key Innovative Technology
Serial, or offsite, NetZero retrofitting — using prefabricated façade and roof elements alongside integrated energy systems — is indispensable for decarbonizing the building sector. It enables faster, simpler, and more cost-effective achievement of climate-neutral building standards compared to conventional renovation approaches.
Proven Success in Systematic Market Acceleration
Non-profit Market Acceleration Teams (MATs) for serial retrofitting — implementing, for example, the award-winning Energiesprong approach recognized by the EU and UN — have successfully scaled these solutions in Europe, bringing together innovation leaders. This has accelerated climate action in the building sector by a factor of five to ten. The current European market volume exceeds €2 billion.
